Rocker Diaphragm Oilless Vacuum Pump Chemker 300, Chemical Resistant, PTFE, 105 mbar, 20 LPM, 1700 RPM, 1/8 HP, 110V

Chemker series are chemical resistant, diaphragm vacuum pumps which can be widely used to hard acidic, basic and solvent vapors by utilizing corrosion proof PTFE on all the wetted surfaces. They are designed to be quiet, safe, maintenance-free, and cost effective vacuum pumps. All wetted parts of Chemker series pump are made of PTFE material which can resist most of corrosive gases. Chemker series pumps are driven by Diaphragm, without the need of lubricant, regular oil changes and maintenance; with no oil pollution. Driven directly by motor with no additional belt-driven transmission; the quality vibration-proof assembly makes Chemker series run at the lowest noise level among all other equivalent pumps. Every motor of Chemker series pumps has a built-in thermal protection device to shut off the pump automatically when overheated and then resume working when the temperature cools down.
